Hi, I had a crown (my first one) put on one of my molars 3 weeks ago. The procedure went without any problems, but since I have had the crown on I started to have other problems and wondered if there might be a relation. I woke up with severe vertigo about 2 days post crown installment. I have had vertigo previously, but always when I had an ear ache or such. This time I had no ear ache or ear problem whatsoever. The vertigo is still a problem that I am having and it has been almost 3 weeks now. I don't have any pain with crown, but was wondering if I might be allergic to something involved with it. I do have multiple allergies. Do you think there might be a relationship or not? Thanks for any insight.
